Deep root feeder and tree irrigater

ABSTRACT

An elongated cylinderical cannister assembly with many small apertures at the opposite ends filled with gravel and fertilizer pellets, is placed near the tree. This insures that water, air, and nutrition is carried to the outer ends of the roots. The deep root feeder is particularly useful in cities where trees grow through pavement openings.

BRIEF REVIEW OF THE PRIOR ART SUMMARY OF THE INVENTION It has now been discovered that if an elongated cylindrical cannister assembly with many small apertures at opposite ends, filled with gravel and fertilizer pellets is placed vertically in the ground near the tree, air, water and nutrition can be carried to the roots of the tree.

The invention as well as other objects and advantages there of, will become more apparent from the following detailed description when taken together with the accompanying drawing, in which:

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of the inventive concept showing the utilization of the deep root feeder contemplated herein;

FIG. 2 shows a cross-sectional side view of the deep root feeder;

FIG. 3 shows a perspective explanation with parts broken away illustrating the inventive concept;

FIG. 4 is another perspective explanation of the method of using the inventive concept.

DETAILED DESCRIPTION Depicted in FIG. 1 is a paved street or road, 10, with an opening, 12, therein, about 3 to 6 feet in diameter. Through this opening it is possible to see the soil, l4, and a tree, 16, planted therein. Under the soil, 14, the tree, 16, has roots 18a, 18b, 18c.

Disposed very near the soil is a cylindrical cannister extending down from the top of assembly 20, the details of which are illustrated in FIG. 2 and FIG. 3.

Cannister assembly, 20, has an elongated cylindrical outer shell housing, 22, made of not readily oxidized material, e.g., a heavy plastic, and includes a lower receptacle section, 24, and an upper neck section, 26. The neck section has an upper wall cover, 28, with a plurality of small apertures, 30. Surrounding the upper wall, 28, is a disc-like flange 32 with lower teeth 34 around the periphery. Within the neck at the bottom thereof is an inner stepped section 36.

Within the outer shell housing 22 is a cylindrical cannister, 38. Cannister, 38, is hollow and filled with gravel, 40, and fertilizer pellets, 42. At the upper end of cannister, 38, is an outer flange 44 which rests on inner stepped section 36 of the housing. The bottom of the cannister, 38, also has apertures, 46.

OPERATION OF THE INVENTION The unit has only three pieces. The housing is 18 inches long, the outside diameter is 4 inches. The lid,

or cover, is formed to fit over the neck in the head of the unit. It is 4 inches in diameter. The head of the unit is flared to extend 1 inch on any side of the unit, to hold it firmly in place, it is 6 inches in diameter.

The cannister is 3% inches in diameter outside, 8 inches in length, has an open top and holes in the bot-' tom.

The cannister, removed from the housing, is filled with fertilizer and gravel. Then it is placed in the housing with the top flange resting on the housing inner stepped section. The cover is then placed over the housing. There is an empty vent space between the top of the cannister and the cover. The cannister is then placed in the soil as shown in FIG. 4, in a vertical position in the last 6 feet of the outer circumference of the canopy of the tree. More than one cannister per tree can be used, for very large trees. Also, one can be used to service several trees. One system will serve an area 10 feet in diameter. a

The operation of the system is best illustrated in FIG. 4 showing a tree, 16, with enlarged root 18a, root hairs 19, the cannister assembly 20 and enlarged leaf 21.

The health of a tree is dependent upon the manufacture of food in the leaves, 21. The leaves, 21, receive nutrients and water from the roots 18a (see FIG. 4). Roots require an intake of oxygen in order to function. One of the root's primary sourcesforoxygen is natural rainfall through the root hairs 19.

In most cities, towns and developments, only a small percentage of rainfall reaches the soil. Storm drains and asphalt paving provide a rapid water run-off, thus tree roots must forage for nutrients, causing greater root extension and perhaps root protrusion through soil and pavement.

This explains the slow death of trees surrounded by asphalt or on parkways orwithin t'he confines of a city.

This system will give any land development the added value of healthy long lasting, beautiful, sought-after trees without sacrificing land-use efficiency. A tree will be able to thrive although its roots are completely covered by an asphalt paved parking lot.

Heres what the Deep Root Feeder will do:

1. Trees can be used efiectively in project designs;

2. Forget about the unnecessary expense of tree removal six months after the property has been opened;

3. Trees can be allowed to stand in parking lots;

4. Tree roots will not burst through foundations or rupture sidewalds or tear up concrete or asphalt.

5. It is possible to plan on property maintaining its natural beauty for as long as trees stand;

6. It is possible to protect the environment now before some form of tree preservation is a legal imperative.

The basic unit of the system consists of an 18 inch deep by 4 inch diameter heavy duty plastic housing which holds a removable inner sleeve cannister which contains time-release nutrients. Liquid fertilizers can also be used.

The housing is set into the ground deep enough. to allow its perforated top to protrude one-quarter inch above the ground. Air and water enter the top and are filtered down, through gravel and ultimately to the roots (see FIG. 4). Housings are placed at 10 foot intervals around the tree. The distance of the ring of housings varies with the size of the overall canopy, for best results they should be placed in the last 6 feet of the trees drip line or directly beneath the outer band of the canopy: the distance of the feeder root ends from the base of the tree.

The fertilizer contained in the unit is concentrated, high in nitrogen content and non-toxic; this means it will not harm tree roots or any vegetation it contacts in its concentrated form. Liquid fertilizers and soil conditioner can alwo be used.

The seven-eighth inch X l 1% inch fertilizer tables break down slowly as water passes through the gravel sifting soil over them. Bacteria in the soil activates the chemical release of the fertilizer.

The system can be installed in minutes and annual servicing can be accomplished in another simple 10 minute operation.

One other point may be considered. One system pro vides enough nutrients to service an area of soil 10 feet in diameter. Any number of trees whose roots feed in that given area can benefit from that unit.

The system, if applied properly and quickly, can save literally thousands of trees that are slowly dying of malnutrition. It can save big trees and nurse smaller ones back to vitality. It can virtually put an end to developers headaches regarding costly, time-consuming tree removal. It can increase land value and guarantee maintenance of the tree aspect of natural beauty. It can prevent tree roots from destroying pavement and foun dations.

In short, the system can simulate a natural environment for trees, making the hostile, unfamilar environment of commercial and residential developments compatible with trees, providing a needed solution to the desperate dilemma of dying trees.
